el Claims,

This invention relates to a boiler construction and the prime object is to provide a tubular boiler trarne or supporting structure, this trame acting as a conduit for the water supply which prevents overheating and destruction of the traine.

Another object is to provide a novel coil mount whereby the coil can be easily and quickly removed. Ior purposes of repair or replacement.

A further object is to provide a novel frame structure which can be easily cleaned when necessary.

Other objects, advantages and features oi invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing Figure l is a side elevation oi rny boiler construction vvith the housing or cover removed.

Figure 2 is a longitudinal sectional View or" one or" the end frame members.

Referring more particularly to the drawing, the numeral i indicates a boiler drum or" Usual and Well-known construction and this boileris supplied with hot water or steam from a double coil 2. A suitable burner 3 is provided below the coil for the purpose of heating the water which moves thru the coil. The burner is of usual and well known construction and may be either gas, oil or the like.

Boilers of the type disclosed in this invention are enclosed ina housing and consequently, the supports for the boiler drum are subject to a rather intense heat. This heat causes rapid oxidation and the supporting structure will fail after a comparatively short length of time.

The supporting traine for the boiler drum l comprises two end members l, 5, each oi which comprises a vertical pipe t, a pair oi short nipples '1, 'i attached to the bottom oi" the pipe e and a pair of vertical pipe sections which form legs to support the boiler drinn. The pipes 8 are closed at the bottom by a cap S. Suitable pipe ttings of standard construction connect the various pipe sections and nipples to form a conduit or passage-way which is filled with water, as will be subsequently described.

A horizontal pipe le connects the end 4 and 5 and the water intake pipe il extends into this horizontal pipe. it will be evident, therefore, that both of the frame members, as well as the horizontal pipe lil will be completely filled with water from the source of supply. A pipe coupling il extends from the top of the pipe 6 into the boiler drum, thereby completing the circuit for the water.

Serial No. 227,920

A threaded plug l2 is provided at the top of each of the pipes S and a second threaded plug i3 is provided at the bottom and when these are removed, the pipe E can be quickly and easily cleaned. A plug is is also provided in the end oi the horizontal pipe lil for the purpose of cleaning this pipe, when necessary. Y'

The double coil 2 is connected to the pipe IB by a T i5 and the upper ends or the coils extend into the bottom of the boiler drum i at i6 and E1. 10 it will be evident that the coil 2 can be removed t or the purposes of replacement or repair by merely renioving the fittings at the top and bottoni of the coils, all of which are easily accessible.

The circulation of water is an upward one thru 15 the coils 2, thence into the boiler drum i, thence downwardly thru the Vertical pipe (i, thence into horizontal pipe iii and into the bottom of the coils. Sediment is dropped in the horizontal pipe it and can be removed when necessary by opening the stop cock or boiler blow out valve attached to one end of pipe le.

i-iaving described my invention, I claim:

l. in a boiler construction comprising a boiler drum, a tubular frame comprising a pair of end members, each of said end members comprising a vertical pipe, a pair of pipe legs attached to the bottom oi said vertical pipe, said vertical pipe extending into the boiler drum at the upper end thereof, a horizontal pipe connecting said end members, and a Water intake extending into said horizontal pipe, screw plugs in the top and bottorn of said vertical pipes and a screw plug in the end or" said horizontal pipe.

2. ln a boiler construction comprising a boiler drum, a tubular frame supporting said boiler, said tubular frame comprising a pair of end members, a vertical pipe in each ci the end members, said vertical pipes extending into the boiler drum at the upper ends thereof, pipe legs attached to vertical pipes, a horizontal pipe connecting the end members and coupled thereto. a coil beloit7 the boiler drum, the upper end of said coil extending into the boiler drum, and the lower end of said coil extending into the horizontal pipe, cleaning plugs in the top and bottom of said vertical pipes and a cleaning plug in the end of said horizontal pipe.

3. ln a boiler construction comprising a boiler drum, a tubular frame supporting said boiler, said tubular frame comprising a pair of end members, a vertical pipe in each of the end members, said vertical pipes extending into the boiler drum at the upper ends thereof, pipe legs attached to said vertical pipes, a horizontal pipe connecting the end members and coupled thereto, a. coil below the boiler drum, a T fitting in the horizontal pipe, said coil being attached to the T tting, a fitting at the top of the coil, said fitting extending into the bottom of the boiler drum and heating means for said coil, cleaning plugs in the top and bottom ofsaid vertical pipes and a cleaning plug in the end of said horizontal pipe.

4. In a boiler construction comprising a boiler 1Y0 drum, a tubular frame comprising a pair of end members, each of said end members comprising a vertical pipe, a pair of pipe legs attached to the bottom of said Vertical pipe, said vertical pipe extending into the boiler drum at the upper end thereof, a horzontal pipe connecting said inembers, water intake means, cleaning plugs in the tops and bottoms of said vertical pipes, and a cleaning plug in the end of said horizontal pipe.
